Dog owner David Bowling said his two 6-month-old pit bull puppies -- Max and Ceasare -- are doing fine now, but were near death after falling ill around Memorial Day.

“We came home about 10 at night. The dogs were playing in the yard, and one of them just fell to his feet and (started) going into convulsions, seizures. His heart was going really fast, and the other one came around the corner and the same thing happened to him,” said Bowling.

Bowling said blood work conducted by a veterinarian’s office indicated the dogs had indeed been poisoned.

“It got to a point where he was so sick where we just hoped he would pass, and we talked to the vet and he said, ‘It's definitely poisoning,’ so three days of throwing up. It was a rough three days,” said Bowling.

Kara Cella said her 4-year-old boxer, Vader, has high toxin levels in his blood and has failing kidneys and liver.

“He’s still losing weight. His kidneys are not where (the veterinarian) wants them. He has no energy. He just sleeps,” Cella said.

Cella told Channel 4 Action News that Vader may have to be put down.

Alice Craig said her 12-year-old pit bull, Dozer, was also poisoned.

“The mailman said there were other dogs that were poisoned on this street, so I became more concerned,” Craig said.

The attack on dogs didn't just create fear and concern among residents, it also prompted Animal Friends to post notices in the area asking for information that could lead to an arrest.

“It's sickening. I mean, it is. This is a case that it's not, ‘I didn't feed my dog today. I forgot to put water outside.’ This is a deliberate. Someone had to think,” said Humane Officer Robert Fredley. “Whatever's affecting the system is what's causing the seizures, the throwing up, the diarrhea, and then the lack of eating, the lack of nutrients, which just adds to the problem.”

Dog owner Demeco Poindexter is furious to hear that someone poisoned dogs in his neighborhood.

“It angers me because this dog is my family, and I’m sure everybody feels that way about their dogs. If anybody hurts someone in your family, you would feel the same way,” Poindexter said.

Linda Jackson said her 5-year-old Chihuahua, Wheezy, used to weigh 17 pounds, but has since lost five pounds after being poisoned in the back yard of her Bennet Street home.

Investigators said Wheezy's symptoms are similar to the five other alleged cases in McKeesport. One of the dogs has since died.

Jackson said she was taking Wheezy to a vet on Thursday.

"I just don't want to happen to him what might happen tomorrow, with him getting put to sleep," she said.

Anyone with information regarding the poisonings is asked to contact police.
